Description

Technical Field

[0001] The utility model relates to the technical field of homogenization and stirring, in particular to a cement grinding aid homogenization device. Background Art

[0002] Cement grinding aid is a chemical additive that improves the grinding effect and performance of cement. It can significantly increase the hourly output of cement, the strength of cement at all ages, and improve its fluidity. Cement grinding aid can significantly reduce the electrostatic adsorption balling phenomenon formed during the grinding process, and can reduce the re-agglomeration tendency of ultrafine particles formed during the grinding process. Cement grinding aid can also significantly improve cement fluidity, improve the grinding effect of the mill and the powder selection efficiency of the powder classifier, thereby reducing the energy consumption of grinding. Cement produced using grinding aids has a lower compaction and agglomeration tendency, which is beneficial to the loading and unloading of cement and can reduce the wall hanging phenomenon of cement silos. As a chemical additive, grinding aid can improve the distribution of cement particles and stimulate the hydration dynamics, thereby improving the early and later strength of cement.

[0003] The main component of the grinding aid is anionic polymer. The grinding aid can be adsorbed on the surface of various tiny particles and generate electrostatic repulsion to disperse them, avoiding sedimentation and coarsening.

[0004] During the grinding process of barium sulfate, water-coal slurry, cement and other slurries, the viscosity of the processed materials can be greatly reduced, which is convenient for material processing, and the viscosity of the slurry is stable after dispersion.

[0005] During the production and use of grinding aids, they need to be stirred and homogenized. Since grinding aids have a certain viscosity and when solid and liquid grinding aids are mixed, the wall sticking phenomenon is more obvious during the stirring process.

[0006] Therefore, we propose a cement grinding aid homogenizing device to solve the existing problems. Utility Model Content

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0020] 1. During use, the cement grinding aid homogenizing device of the utility model can introduce liquid and solid cement grinding aids into the tank body, and then the shaft moves down, and the rotating mixing head mixes and homogenizes the materials inside the tank body. During this process, the shaft does not drive the scraper to rotate, and then the personnel can control the shaft to stop rotating regularly, insert the positioning bolt on the collar into the cushion seat, so that the collar and the cushion seat are integrated with each other. At this time, the rotation of the shaft can be controlled to drive the scraper to rotate along the inside of the tank body, so that the materials adhered to the inside of the tank body can be scraped off to participate in the mixing and homogenizing process. When the scraper does not need to rotate, it is only necessary to keep the positioning bolt away from the cushion seat. The utility model can effectively solve the wall sticking phenomenon during the homogenization process of the cement grinding aid, ensure that the materials are mixed evenly, and facilitate the subsequent use of the cement grinding aid.
